SPRING-WHEEL.

Specification of Letters Patent.

Application filed March 17, 1906. Serial-No. 306,680.

To all whom it may concern:

Be it known that we, FELIX J. BIEHN and Or'ro BIEHN, citizens of theUnited States, residing at Madison Lake, Blue Earth, State of Minnesota,have invented certain new and useful Improvements in Sprin -VVheels; andWe do hereby declare the fo lowing to be a full, clear, and exact cle--scription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to wheels,andmore particularly to spring-wheels,and has for its object to provide a wheel of this kind which will besimple, which will include few parts, and which may be produced at lowcost.

The primary ob ect of the invention is 'to provide a wheel of aresilient nature which will absorb the shocks incident to passing overrough or'uneven surfaces.

Other objects and 'advantageswill be ap-' parent from the followingdescription.

In the drawings forming a portlon of this specification, and in whichlike'numerals of reference indicate similar parts in the several ure 1is an elevational view of the eel. Fig. 2 is a vertical sectional view.Fig. 3 is a section taken at ri ht angles to Fig. 2 on line 3 of'Fig. 1.I ig. 4 is an enlarged detail section of one of the spokes. Fig. 5 is aperspective view showing the memone of thespokes disconnectedthedrawings, there is rising a hub including a air of spaced'annu ar plates5, the openings of which register for the reception of a boxin 6, andthe lates thus form what are, in e feet, space circular flanges lym inparallel relation. The flanges are eac 1Erovided erforations 7, t eperfo ining in anges a1 ivotins 8, and pivotally present w Referring nowto rations of the two the reception of on of a spoke, there being t us aplurality-of these spokes having erforations 9 therein at their innerends w 'ch the pivot-pins 8 are engaged. Eachf spoke consists of twotelescoping sections-an inner section 10, in which the opening 9reformed, and an outer section 11, havin at its outer end aperforasection 10has alongitudiual chamber 12 therewithin which opensthrough the outer end of in the county of ,felly 19, there lar plates, aoxing engaged gaged in each pair pairs for of t ese ins is the'inner theperforation 9. The

The sections 11 of the several spokes, as will be readily understood,are held by the springs 16 yieldably against inward movement, and t ,eouter end of each of these sections 11 lies between a pair of inwardlys18, which are carried by a eing one pair of these wings 18 for eachspoke, and the erforations 9 of the"sections 11 register wit aliningpairs of perforations 20, formed in the the rece tion of pivot-pins 21.be seen t at the sfpokes, the are susceptible o sl' ht pivotal movementat their. connections. ashers 22 are. engaged with the pivot-pins 8 and21 at opposite sides of the s okes to prevent lateral movement of thespo es upon the pivot-pins, and it will be seen that new washers may befor worn onesg extending It will thus 1 4 What is claimed is hub, andthe felly Wings 18 for substituted A. wheel com risinga of spaced amiuplates, said plates having pairs. perforations therethrou h, a pivot-pinenof pe orations, spokes including inner and outer sections and havingperforations at their inner ends in which the ivot-pinsare engaged, saidinner sections aving chambers therewithin opening through their, outerends and havin sections being engaged within the chambers within] the otalining reduced innerl portions and resultant shou ders, said outer} jroo of the inner sections and having reduced por- I into the reducedportions of rings engaged with the reduced portions .0 the outersections,
